ADDING AND RECORDING MACHINE.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed Kay 25, 1917. Serial 1T0. 170,884.

To all whom z'tma concern:

Be it known is at I, BIRNEY DYSART, a citizen of the United States, residing at the cit; of Cincinnati. county of Hamilton, and State of Ohio, have invented a new and useful Adding and Recording Machine, of which the following is a specification.

This invention relates to adding and recording machines. Some of the addin and recording machines now on the mar ct are equipped with a limited number of special types or logotypes, but the number thereof which can be used on any particular machine is so limited that their extent of use for making out statements and performing other classes of similar work is greatly restricted.

I am aware that separate ty )ewriting or recordin means have been used in cooperation wit the regular printing or listing mechanisms of adding machines. so that a comparatively wide range of words and characters may be printed in any desired relation to the amounts and the totals thereof as listed by the recording mechanism of the adding machine; but I know of no adding machine whose regular recording instrumentalities under control of the difl'erential mechanism are capable of producing more than a very limited number of words or the number thereof being usually determined by the number of special types or logotypes which can be carried by a single type-carrier at one time.

.Since it is essential that the type bars or type blocks, on which the 10 otypes or special characters are engrave shall be securely retained in their sup orts on the type-carriers of an adding mac line, as these machines are now constructed only those words or special characters can be printed for which provision has been made in the assembling of the machine during the manufacture thereof. It is a consequence of this condition that the removal of one set of logotypes and the substitution of others in place thereof requires the services of a skilled mechanic provided with the necessary tools.

My present invention relates to the nuting mechanism of the machine, and it has particular reference to that class of adding and recording machines which includes a series of type-carriers operable side by side under control of diflerential mechanism to record items or amounts set up in the differential mechanism, and to o erate the transfer mechanism for causing t e adding mechanism of the machine to add the items or amounts listed.

An object of my present invention is to make provision for the equipment of ma chines of the class mentioned with an unlimited number of words and special characters, which may be varied or changed at will, such equipment including a series of type bars or type blocks for printing such words or abbreviations as it may be desired to print in connection with the work performed by the listing mechanism of the adding machine, and means for removably supporting said type-bars or type blocks upon one of the type-carriers under control of the differential mechanism of the adding machine. By Srovision of such equi ment the proper wor or abbreviation wil. be automatically listed or printed in alinement with the printed items or amounts listed by the addin machine and at the same operation.

In t e attainment of the foregoing object, I have provided means whereby the special types of logotypes mounted on the type-carriers of the adding machine may be easily and quickly removed from their supports and any others desired substituted by an ordinary operator of the machine without the services of a skilled mechanic and without the necessity of tools of any kind. In this way I make it possible to print any number of words or special characters by the ordinary recording mechanism of an adding machine, the number of such words or special characters'being limited only by the number of logotypes or special types that are available.

For convenience I have illustrated my invention embodied in a Dalton adding machine, though it will be understood that its use and capability is not limited to that specific machine.

The Dalton adding machine in which I have illustrated my present invention is manufactured in substantial conformity with the disclosures of Hubert Hopkins Patent No. 1,039,130, dated September 24, 1912. The machine of said patent comprises a series of ten numeral key levers 1 having their operating keys 2 arranged in convenient manner in a key board. The key levers are operable to set the stops 3 of the differential mechanism to represent the digits of the numbers or amounts to be recorded and added by the machine. Said .maehine also includes a series of type-carriers 4 suspended from a shaft 5 and actuated in one direction by springs 6, as required to position said type-carriers for recording the numbers or amounts set up in the difi'erential mechanism. The type-carriers are returned to their idle positions or starting points by a rod or bail 7 supported transversely in front of the vertical portions of the type-carriers by swinging arms 8 also supported by the shaft 5 from which the type-carriers are suspended. After each amount or number has been recorded the type-carriers are restored to their starting points by the rod or ball 7. Each type-carrier is coiiperatively related with the rack 9. The racks 9 are also sus ended from the shaft 5 and cooperate wit the diflerential stops 3 to limit movement of the type-carriers and to stop them side by side to position the printing type in alinement for the purpose of printing or listing the items or amounts set up in the differential mechanism. The racks 9 also operate the adding pinions 10 in adding and transferring opera tions in the well understood manner, as described in said Hubert Hopkins patent and as exemplified in the commercial Dalton 65 adding machine,

- trol 0 Each type-carrier supports a series of movable type blocks 11 which are selectively positioned side by side adjacent to the platen 12 under control of the differential mechanism to record the numbers set up in the difl'erential mechanism. After the type-carriers have stopped, the type driving hammers 13 operate to drive the alined type to list or print upon the paper operating around the platen.

By my present invention certain of the type-carriers are equipped with means for selectively mounting thereon and removing therefrom special type blocks for printing special characters, or words, or abbreviations thereof in alinement with the numbers or amounts listed by the type 11. The special type-carriers, in the illustrated embodiment of the invention, are also under control of the differential mechanism, so that 85 at the same operation at which any number or amount set up in the differential mechanism is printed, a proper identif ing character, word or abbreviation may e printed in ahnement therewith, such for instance as a date, or the abbreviations Dr., Cr., Bah, Com., Dis, and various other commercial words or abbreviations. Although I have illustrated only one of the type-carriers thus equipped, it is readily apparent, that others may be similarily equipped if desired. While the logotype-carrier illustrated is under conthe differential mechanism, it is clear that it may be otherwise controlled, and the invention is not limited to control by the difl'erential of the adding machine.

The type-carrier with which I have illustrated my present invention is the one in the highest numerical order and is at the extreme left relative to the operator facing the machine. This type-carrier is preferably s aced from the adjacent type-carrier in t c next lower numerical order and has affixed thereto a type supporting case 14. The side edges 0 the case 14 are turned toward and bear against the type-carrier. The side walls of the case thus arranged are provided with matching openings or slots in which the type blocks are mounted for lon 'tudinal movement toward the platen w en driven by the hammers 13 and away from the platen under control of the return levers. The case 14 is secured to the type-carrier by screws 15 assing through the case and engaging in t readed holes in the type-carrier and having the ends thereof counterpunched to prevent them from working loose, thus permanentl securing the case to the type-carrier an preventing the screws from working loose. 25

The special type which I have provided are formed on the inner ends of the s cial type bars 16, said type bars having eads 17 contacting wi th t e inner edge of the type-carrier and limiting outward movement 130 1 in the notches in thereof. Said type bars are also formed with shoulders 18 on their outer ends adapted to contact with the type case 14 and limit inward movement of the type bars.

The mechanism for actuating the type bars outwardly after they are driven to print comprises a lever 19 pivotally supported on' the type-carrier at the point 20 and enga 'ng with shoulders on a number of the type locks; and a cooperating lever 21 plvota ly supported on the type-carrier at the point 22 and engaging with shoulders on the remaining type blocks; said two levers having lateral extensions adjacent to their pivots which are connected by a spring 23 by which said levers are actuated to return the type blocks to their normal posi tions after operation by the cooperating hammer.

The type blocks 16 are held in osition by a retaining device which is so stantially U-shaped in elevation and consisting of a wire bent to provide two arms 24 removably mounted between the type blocks 16 and the type-carrier supporting them and thus holding the types in position adjacent to the inner wall of the case 14, but leaving them loose and free for movement by the hammer cooperating therewith and by the levers 19 and 21. The arms of the retaining device pass through openings in the upper end of the case 14 and contact with the side walls of the type case. Each of said arms is formed with a slight crimp or bend 25, said crimps or bends eing arranged to engage which one of the type blocks operates, thus preventing the retaining device from being displaced in the operation of the machine but permitting it to be readily withdrawn by engagement with the upper portion 26 which connects the side arms thereof. The heads or shoulders 18 are of less thickness or width than the depth of the notches in which the type blocks are mounted, and when the retaining device 24 is withdrawn the type blocks may be removed from the case by inward longitudinal movement. The heads or shoulders 18 may also pass the levers 19 and 21 when being withdrawn from the case.

Each of the type bar heads 17 may be provided with one or more characters. If desired the designation of the year may be printed upon one of the type bars and any desired words or abbreviations, or other identifying data may be upon the remaining type bars. The matter to be printed by the special type may be varied at will by changing the type blocks when desired.

In the specimen example illustrated in Fig. 10 one of the type blocks has printed the designation of the year, as shown as A, and abbreviations of months are printed by other type blocks in alinement with the days of the months printed in the column B, and

a date co umn and the item column.

the items or amounts printed in the column C.

In performing work of this character each line of printing includin the designation of the month, the day of t e month and the item or amount corresponding to that da is printed at the same operation of the printing mechanism, the type-carriers being controlled in their movements b stops set in the diflerential mechanism. l hus the sto of the dilferential mechanism correspon ing to the type block having thereon the designation of the year is set in the highest numerical order, and that type-carrier is then operated in the usual manner and printing is effected by operation of the hammer against the type as in the ordinary operation of the machine in printing any number. Then, when it is desired to print the designation of a month and the day of the month in alinement with an amount, the stop in the differential mechanism corresponding to the t pe block that will print t e designation 0 the particular month in question is set in the highest numerical order, and stops in the differential mechanism in next adjacent numerical orders are set for printing the numerals of the da of the month, and also the stops in the di ferential mechanism for printing the amount are set by the operation of the keys in the usual way. After the stops have thus been set the type-carriers are operated and the word or abbreviation, the date and the amount are all printed at one operation on the same line.

The Dalton and other addi machines now on the market are provide with well known mechanism for preventing the print ing of ciphers between the difl'erentcolumns, so that no ciphers will be printed between the date column and the column containing the items or numbers. It is contemplated that my invention will be employed in such machines and the specimen example illustrated in Fig. 10 is an example showin the ciphers omitted between the Such machines are also equipped with means for preventing the addition of the numbers corresponding to the dates, but will permit transferring or carrying over from lower orders into the adding mechanism corresponding to the date column. Since such mechanism is well known, it is unnecessary to illustrate or to specifically describe the same herein.

On some occasions it may be desired to have one or more of the type blocks permanently mounted, so that they cannot be removed. For instance, it may be desired to retain the levers 19 and 21 from becoming displaced when any of the type blocks are removed. To obviate that trouble one of the type blocks in the series controlled by the lever 19 and one of the type blocks in the series controlled by the lever 21 may be permanently mounted. Preferably the upper type block in the series controlled by the lever 19 and the lower type block in the series controlled by the lever 21 will be permanently mounted, so that it cannot be moved when the retaining device 24 is removed. For holding said two type blocks permanently in position and preventing dislocation thereof when the retaining device 24 is removed, two lugs 27 are formed on the type-carrier opposite the upper type block and also opposite the lower type block to prevent lateral movement of said type blocks when the retaining device 24 is removed. Thus the upper and the lower type blocks will be permanently retained from displacement, thereby holding the levers 19 and 21 in proper position, while the remaining type bloc s are being interchanged.

11 Figs. 8 and 9, I-have illustrated a modified or alternative form of retaining device for the type blocks. This modified or alternative form of retaining device consists of a resilient loo 28 adapted to pass into the same notch in which each type block operates and having a bent or hooked end 29 adapted to engage in a hole in the typecarrier to prevent displacement thereof during operation of the type-carrier. Thus there is an individual retaining device for each type block so that any selected ty e block may be released and withdrawn wit out loosening an of the others.

It will be un erstood, of course, that in illustrating the specimen example in Fig. 10, I have in no sense limited the invention for use in printing any specific word or abbreviation. The essence of the invention is the provision of means or mechanism for the equipment of some of the usual typecarriers of the adding machine for printing an desired words or abbreviations. Preferabl y also the type-carrier in operatin to rint the words, abbreviations or other ata, is controlled by the differential mechanism of the adding machine so that the typecarrier may a so be used when desired or printing digits of numbers.

It is appprent that the form of the invention may e varied extensively without departure from the s irit and scope of the invention, and also t at the use of the invention is not limited to arcuate type-carriers upon which I have chosen to illustrate it for convenience; nor is it necessary that the logoty e-carrier shall be under control of the diEerential mechanism. Any other suitable means for controlling the logotype-carrier may be employed.
